Abstract
Abstract Solar energy is collected by collector means supported in space by geostationary satellite and directed to an air buoyant intermediate platform at a position within the upper atmosphere. The laser energy is there converted to microwave energy and beamed down to earth.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
A solar energy system comprising: a space vehicle supporting means for collecting solar energy and laser means for using the collected solar energy to form a laser beam directed towards a receiving position within the upper atmosphere of the earth, an air-buoyant intermediate station for floating at said position within the upper atmosphere and supporting means for receiving said laser beam, means for converting the energy of the laser beam to microwave energy, and means for directing said microwave energy as a beam towards a ground receiving position on the earth's surface, and microwave energy receiving antenna means at said ground receiving position.
Claim 2
Dependent Claim
103 words
A solar energy system comprising: a space vehicle supporting means for collecting solar energy and laser means for using the collected solar energy to form a laser beam directed towards a receiving position within the upper atmosphere of the earth, an air-buoyant intermediate station for floating at said position within the upper atmosphere and supporting means for receiving said laser beam, means for converting the energy of the laser beam to microwave energy, and means for directing said microwave energy as a beam towards a ground receiving position on the earth's surface, and microwave energy receiving antenna means at said ground receiving position.
Claim 3
Independent Claim
96 words
A method of providing energy, the method comprising: Collecting solar energy at a position in space, using such energy to form a laser beam and directing said beam towards a receiving position in the upper atmosphere of the earth, receiving the beam at said position by laser energy collecting means supported by an air-buoyant intermediate station, converting the laser energy to a beam of microwave energy and directing the beam towards a ground receiving position on the earth's surface, and receiving said microwave energy beam by means of an antenna system at said ground receiving position.
Claim 4
Independent Claim
96 words
A method of providing energy, the method comprising: Collecting solar energy at a position in space, using such energy to form a laser beam and directing said beam towards a receiving position in the upper atmosphere of the earth, receiving the beam at said position by laser energy collecting means supported by an air-buoyant intermediate station, converting the laser energy to a beam of microwave energy and directing the beam towards a ground receiving position on the earth's surface, and receiving said microwave energy beam by means of an antenna system at said ground receiving position.
